loadFromXML(fis)

[James Howerton]

Hello
I am trying to use the loadFromXML() load a properties file and

I don't understand the example because it is not reconizing the

dtd.
Is the example I am using wrong?


[code]public static void main(String[] args) throws

IOException,
FileNotFoundException, PropertyVetoException,

ProfileException, LoginException {
LoadXMLProperties lp =new LoadXMLProperties();
lp.loadXML("ModelResources_1.properties");
DerbyDAOFactory ddf =new DerbyDAOFactory();
ddf.buildDB();
createJDesktopPane();
XMLReaderComboBox rc = new XMLReaderComboBox();
} [/code]



[code]package model.dao;


import java.util.*;
import java.io.*;
import java.io.FileNotFoundException;
import java.io.IOException;


/**

* @author depot
*/
public class LoadXMLProperties {
public LoadXMLProperties(){

}
public void loadXML(String path) throws FileNotFoundException,

IOException{
Properties prop=new Properties();
FileInputStream fis=new FileInputStream(path);

prop.loadFromXML(fis);
prop.list(System.out);
System.out.println("\nThe XML property:

"+prop.getProperty("foo"));
}
}[/code]



[b]ModelResources_1.properties in XML format[/b]

[code]<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE properties SYSTEM "properties.dtd">
<properties>
<comment>Hi</comment>
<entry key="foo">bar</entry>

Looks to me like you've declared your DTD to be in the same directory as your XML... at least there's a relative URL in your <!DOCTYPE> declaration, so that's what it means.

But then you went and passed a FileInputStream to the parser. So the parser has no idea where the XML is, so it just looks in your current working directory instead. Which is probably wrong. So just pass a File object to the parser, so it knows where the document is. And do make sure that the DTD and the XML document are in fact in the same directory.

(In future it would be better if you posted formatted code, too. Your post was devilish hard to read.)
